Marshmallow Blaster Modular Breech - 35mm MegaXL Barrel

Update 2024/08/13: Update to all files to now use my Cruller thread profile for printability and QOL. These will have 0 backwards compatibility, so print only v4 options for use together and you'll need v4 for my future expansion parts. More thread tolerance can be added on request.

Update 2024/06/21: Welcome to iterative design. V3 files have adjustments to thread fitment and the best oring barrel retention I've seen yet. All file versions are functional, but each newer versions will be nicer to use.

Update 2024/06/20: Update design for easier printability. Oring retention is still a bit wip to optimize results. 

To be paired with my https://www.printables.com/model/918730-marshmallow-blaster-modular-breech , I've created a super simple method to attach a 31mmx35mm acrylic tube to launch Mega XL at frankly frightening velocities. Simply thread the 35mm_adapter onto to the module breech base, slide the barrel into it, add an oring (I used one from a Caliburn), then tighten on the 35mm_barrelnut to lock it in place.

I reccy 2 walls/10% infill as minimum, but 3 walls/20% wouldn't hurt anything. Tolerances are somewhat snug, especially on the threads.
